Can sipi.bot Stop Prompt Injection?
sipi.bot won't detect an injection — but it makes injection pointless for spending. The decision path is a deterministic rules engine, and rules can't be talked into approving anything.
Why detection isn't enough
Injection detection is probabilistic; a bypass is always possible.
Even a detected injection needs something to stop the money from moving.
What sipi.bot does instead
The firewall never asks a model whether a transaction is OK. A rule either matches or it doesn't.
An injected instruction can't add a merchant to the allowlist, raise a cap, or approve a block.
The honest caveat
sipi.bot protects the money path. For content-level injection defense, pair it with a detection tool.
FAQ
Can an injected prompt approve a purchase?
No. Approvals come from rules, not from model output. Unknown merchants stay BLOCKED.
Do I still need injection detection?
Yes — for everything outside the money path. sipi.bot makes the spend damage impossible; detection protects the rest.
Is the decision path really model-free?
Yes — deterministic rules only, ~5 ms, no LLM in the loop.
